Hi all,
first of all, excuse me for my terrible English.
I'm a cake newbie and I need a little help understanding the ajax
rendering.
Using Fiddler I see that after an "ajax update" a lot of useless stuff
is sent to the client.
I'using the following pattern:
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
/* ~ index.thtml ~ */
$ajax->div("divT");
// div1 contents
// for example, a table with a 'Delete' link entry like
// $ajax->link('Delete', "delact/{$id}", array('update'=>'divT'));
// which delete the current row
$ajax->divEnd("divT");
// view other contents...
/* ~ controller (part of) ~ */
function delact($id)
{
// leave out all various checks
// Controller uses the 'RequestHandler' component
// and 'Html', 'Javascript', 'Ajax' helpers
$this->RequestHandler->setAjax($this);
$this->Entity->del($id);
$this->set(*table contents/rows with an Entity->findAll(...) query*)
$this->render('index');
}
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
This code returns to the client the HTML table, in the javascript
__ajaxUpdater__ variable, and ALL of the contents that follow the
'divT' div.
So, if div is followed by 10Kb of HTML, all this markup is sent.
Using the $this->render('index', 'ajax') instead of setAjax($this)
give the same results.
Is this pattern wrong? Is there a most efficient way to send ajax
content to the browser?
Thanks.
Riccardo
